20090066750 | Forceless support frame for printhead shuttle in digital printers - In a digital printer the elements involved directly in the print process, which are located on a shuttle assembly are mounted upon a metrological frame which is isolated from the base frame by vibration dampers. Because the elements of the shuttle drive systems, such as a belt drive system having a motor and pulleys, are mounted upon the base frame, the drive and reaction forces from the motor drive systems are led to the base frame while the shuttles assembly is guided by the force-free, vibration free metrological frame. This allows for higher accuracy during printing as the metrological frame serves as a vibration free reference element. | 03-12-2009 |
20090211469 | Double shuttle configuration for digital printers - A printhead positioning system is provided wherein the shuttle assembly is split up in a printing shuttle, having a high accuracy positioning capability and a utility shuttle needing only a low accuracy positioning system. Due to this split-up the mass of components which have to be positioned accurately is greatly reduced and therefore making it easier to position the lighter load accurately and allowing for use of cheaper drive systems while maintaining the high accuracy in printing. | 08-27-2009 |

20080288114 | Method and System for Control of a Compliant System - The invention relates to the control of an actuator system comprising an actuator and a load that is connected to the actuator by a drive chain comprising a compliant element. The load is positioned by controlling the actuator, which control of the actuator comprises at least the feeding of one or more reference signals to the actuator. To compensate for drive chain compliancy the invention proposes to generate a main reference signal component based on performance specifications of the system and to generate an additional reference signal component, which is adapted to compensate for predetermined jerks induced in the actuator system by the main reference component. The main reference signal and the additional reference signal are superimposed and fed to the actuator. | 11-20-2008 |

20130346764 | Acoustic Noise Mitigation Using Periodicity Disruption - In one or more embodiments, a fixed time interval for a system is determined. The fixed time interval corresponds to time between clock ticks. A random time interval is determined based on the fixed time interval and an offset. One or more electronic components affixed to a motherboard are transitioned to a new power state when the random time interval has elapsed. By introducing a randomization to the timing element to a control signal that drives the power state transition, a periodicity for the system is disrupted. The disruption in periodicity mitigates acoustic noise generated by vibrations in electronic components and motherboards affected by current and/or voltage transitions. | 12-26-2013 |
